解决方案 »

  1.   

    把<filter>和对应的<filter-mapping>紧连着。别分开。java.lang.ClassCastException: org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor cannot be cast to javax.servlet.Filter都匹配错了
      

  2.   

    OpenSessionInViewInterceptor cannot be cast to javax.servlet.Filter
    类型转化错误，你是不是在配置文件中将拦截器当成过滤器了
      

  3.   


    这是两个完全不同的概念啊，javax.servlet.Filter 过滤器
    拦截器interceptor，spring的主要功能了，
    还是让大神给你详细解释吧
